Answer: the first one: h+5/2=4.
Step-by-step explanation: you Subtract 5/2 from both sides.
h+5/2=4
h+5/2-5/2=4-5/2
Then you subtract: h=4-5-5/2
h=3/2
h+5/2-5/2=4-5/2.
h=3/2
In conclusion: H=3/2. Then it goes in the second column.
The second one: 120/h=10.
Step-by-step explanation: 120/h=10
hx(this is an x as in multiply)120/h=hx10
120=hx10
120=10h
Divide both by 10
120=10h
120/10=10h/10
120/10=10h/10
12=10h/10
12=10h/10
12=h
Then move the variable to the left:
12=h
h=12
120/10=10h/10
h=12.
The third one: divide 10 by 1/2 which equals 20.
The fourth one: h-3=9
Add 3 to both sides:
h-3=9
h-3+3=9+3
Simplify:
h-3+3=9+3
h=9+3
h=9+3=12
h=12
h-3+3=9+3
H=12
Solution: h=12
Which goes in the 3 columns.
then the last one: 5h=60
5h=60
divide 5 on both sides:
5h/5=60/5
5h/5=60/5
h=60/5
Divide:
h=60/5
h=12
5h=60/5
h=12
